01 - In a large skillet over medium heat, cook ground beef while breaking it apart with a spoon or spatula until fully browned. Drain off any excess fat.
02 - Add taco seasoning and water to the browned beef. Stir well and allow the mixture to simmer for 2 to 3 minutes until thickened. Remove from the heat and set aside to cool slightly.
03 - In a large salad bowl, add chopped romaine lettuce, halved cherry tomatoes, diced red onion, black beans, corn, and shredded cheddar cheese.
04 - Gently fold the slightly cooled taco beef into the salad ingredients, distributing it evenly.
05 - Just before serving, add crushed Doritos and your preferred dressing. Toss gently to ensure all ingredients are well combined.
06 - Divide the salad among plates and serve at once while the chips maintain their crunch.
